The quality of window and door aluminum profiles is determined not only by material selection and extrusion precision but also critically by surface treatment. We provide comprehensive surface finishing solutions including anodizing, electrophoresis, powder coating, PVDF fluorocarbon coating, and wood grain finishes.
The aluminum profiles are immersed in an acidic solution and undergo electrolytic oxidation to form an oxide film. Anodizing enhances the corrosion resistance, hardness, and surface smoothness of the aluminum profiles. It can also be used with dyeing agents to achieve different colors.
Class of oxide film: AA10; AA15; AA20
Surface type: Matte; flat
Color: Silver white; bronze; champagne
Fetures: Corrosion resistant; durable; shining and decorative
The charged aluminum profiles are immersed in a coating solution in an electrolytic tank. Through electrophoresis, the coating evenly adheres to the aluminum surface. Electrophoretic coating provides good weather resistance, color stability, and a smooth and uniform coating.
Corrosion resistance of composite film: ≥9.5 level
Paint film cohesive: Zero lever
Paint film hardness: ≥3H
Surface: Matte; flat; high brightness
Color: Silver white; bronze; champagne
Features: Corrosion resistant; durable; smooth and shining
Powdered coating material is sprayed onto the aluminum profiles, and then melted and cured at high temperatures. Powder coating offers durability, corrosion resistance, and a pleasing appearance. It is also environmentally friendly.
Coat thickness:40-120um
Coat shock resistance: No cracking or fall off after shock test
Coat cohesion: Zero lever
Surface type: Highly glossy; semi glossy; matte
Color: Ral color
Features: Variety of colors
PVDF coating, a type of spray coating, utilizes a PVDF resin-based paint that provides exceptional resistance to weathering, UV radiation, and chemicals, making it suitable for demanding outdoor applications.
Coat thickness:30-65um
Coat shock resistance: No cracking or fall off after shock test
Coat cohesion: Zero lever
Glossiness: 60°
Features: With metallic luster, bright color, high weather resistance
This process involves transferring wood grain patterns or textures onto the aluminum profiles using a transfer method. It gives the aluminum profiles the appearance of wood while retaining the advantages of aluminum, such as weather resistance and corrosion resistance.
Surface texture: Wooden; marble
features: Wood-like visual experience
The most widely used aluminum alloys for window and door profiles are 6063-T5 and 6061-T6, chosen for their optimal balance of strength, formability, and corrosion resistance.
Both alloys undergo precise alloying and tempering processes to ensure consistent performance in fenestration applications, complying with international standards like EN 755, ASTM B221, and GB/T 5237.
Our factory is equipped with 6 extrusion production lines to efficiently manufacture window and door aluminum profiles. We have one anodizing and electrophoresis line, as well as two vertical and two horizontal spraying machines for surface treatment. Additionally, we operate two sandblasting machines and six wood grain transfer printing lines, allowing us to provide a variety of aesthetic finishes for our window profiles. To support our production, we also have furnaces for casting aluminum bars, aging furnaces, annealing furnaces, water cooling treatment equipment, and machining tools, ensuring comprehensive capabilities for high-quality output.
We have one-stop production capabilities, providing services from aluminum extrusion profiles to surface treatment, additional processing and finished door and window assembly.
We support packaging according to your needs, such as outer boxes with your logo, customized profile packaging. If there is no special instructions, we will use our regular packaging.
Our Window & Door Division specializes in global customization of high-quality windows, including glass integration. We support a wide range of window types to meet diverse architectural needs:

For custom aluminum extrusion projects, we accept a variety of drawing formats, including CAD files, STEP files, and PDF files. However, for extrusions that require additional machining processes, it’s recommended to provide STEP files, as they ensure precise 3D modeling for machining accuracy.
While PDF files are acceptable, converting them into CAD drawings may result in the loss of certain details, requiring us to manually redraw the design, which could increase lead time. For the fastest and most accurate quotation, we recommend providing CAD files (e.g., DWG/DXF) and STEP files to ensure efficient design evaluation and pricing.
Mold fees are an essential part of the custom aluminum extrusion process. Since every order requires a uniquely designed mold tailored to specific requirements, these molds cannot be used for other products. Therefore, the mold fee is necessary and non-negotiable.
We require 100% upfront payment of the mold fee before mold development begins to ensure timely production. However, as a token of appreciation for your support, we offer a refund of the mold fee or equivalent discounts once the order reaches a certain production volume. Specific policies can be discussed based on your order volume and collaboration details.
Our minimum order quantity (MOQ) varies depending on the size of the product. For smaller-sized products, the MOQ is typically 500kg, while for larger-sized products, it is 2 tons.
We will specify the exact MOQ requirements during the quotation process. If your order quantity does not meet the MOQ, we can still arrange production, but an additional fee will be applied to cover mold preheating and production setup time. Rest assured, this extra fee will be reasonable, and we aim to keep it as minimal as possible to ensure smooth cooperation.
Packaging can be customized according to your needs. Options include using protective film or paper to separate and protect the surface, or foam film for additional surface protection. Products can be palletized or packed into cartons, and the quantity per pallet or carton can be specified by the customer.
The standard packaging involves bundling several pieces together with plastic wrap and then securing them onto pallets. Any packaging requirements beyond the standard will be accommodated, and the associated costs will be clearly provided to the customer.
Mold production typically takes 7 days. After the sample is confirmed, producing a full container load of 26 tons generally requires 14 days for extrusion alone. If surface treatment is required, an additional 3 days will be needed. For machining, extra time will be required depending on the complexity and volume of the machining work. The exact additional time for machining will be determined based on the specific processing requirements.
Aluminum profiles are naturally corrosion-resistant due to the formation of a thin, protective oxide layer when exposed to air or water. This anodizing layer is stable and self-repairing, meaning that even if the surface is scratched or cut (such as at exposed ends or during processing), the aluminum will not rust or corrode like iron or steel. Instead, the exposed areas will quickly form a new oxide layer, providing continuous protection against further oxidation.
With proper design, installation, and maintenance, aluminum profiles can last for decades, even in challenging environments. For example, untreated aluminum can easily withstand 20-30 years in outdoor applications, while profiles with surface treatments like anodizing or powder coating can last even longer, often exceeding 50 years. This makes aluminum an excellent choice for applications where durability and long-term performance are essential.
Our production equipment is designed for the metric system. If the drawings provided are in the imperial system, we will convert them into metric units for production to ensure accuracy.
It is important to note that while we can machine imperial-threaded holes for fasteners, if you require us to supply matching imperial fasteners, they may not always be available in stock. Custom orders for imperial fasteners typically require a large volume for production. Please consider this when planning your project.

System doors and windows represent a modern approach to fenestration design, where every component is engineered and tested as part of a cohesive unit. Unlike conventional door and window assemblies—where profiles, glass, and hardware are selected separately—system solutions prioritize integration, performance, and durability from the outset.
